Hello to everyone, my BSD opto board is suspected faulty and has some strange reparations from previous owners.
I wanted to fix it and looked on the manual BOM for indetifying the parts.
I have seen that also NBA fastbreak and shadow share this board with BSD but some resistor (see R9, R12, L1) values on the BOM seems to differ from manual to manual.
Is this some kind of update that bally/williams did to the board through the years?
what do you think? Which BO should i use for my final fix?
Thanks!
